9 Claims. (Cl. .Z4-205.14)

This invention relates to sliders as used on separable fastener devicesto couple the Stringers of such devices by movement of the sliders alongthe stringers. More particularly, the invention deals with sliderdevices employing what I term a friction type of cam lock wherein thelock element is tensionally supported in engagement with the Stringerscoops or links and cammed out of engagement therewith in free movementof the slider along the stringers. The novel features of the inventionwill be best understood from the following descriptions when takentogether with the accompanying drawing, in which certain embodiments ofthe invention are disclosed, and in which the Separate parts aredesignated by suitable reference characters in each of the views;

andin which:

Fig. 1 is a side and sectional view of a slider made according to myinvention.

Fig; 2 is an exploded perspective view of some of the slider parts toclearly illustrate the assemblage of the parts.

Fig. 3 is a side View of a modiiled form of hood or yoke I employ, on areduced scale; and

Fig. 4 iS a View similar to Fig. 3 showing another modification.

In Figs. 1 and 2 of the drawing, I have shown a slider I8 comprising topand bottom walls II and I2 joined at one end of the slider by aconnecting web I3, the walls II and I2 having inwardly directed sideanges `I4 and; I5 respectively, by deiining the channel I6 of theslider. This Slider body, generally Speaking, is of more or less commonstructure, and is adaptable for use on separable fastener stringers,well known in this art, to couple and uncouple the scoops of theStringers.

To diagrammatically illustrate the locking principles of the slider, Ihave indicated in Fig. 1 of the drawing two scoops I'I arranged in thechannel I6 and engaged by lock elements I8 depending irom the sides of alock member, hood or yoke I 9.

The hood or yoke I9 is in the form of an elongated box shaped enclosurehaving a top wall 20, end walls 2I and 22 and side walls 23 and 24, noteFig. 1. The Vlocky elements I8 form downward extensions to the sidewalls 23 and 24, as will clearly appear from a consideration of Figs. land 2. The side walls have rcentrally thereof elongated andlongitudinallyI extending apertures 25 adjacent the ends of which are inclined apertures 26 and 21. For'sim'plicity in description, and byreasonof lsin'iilalrityincon-h Struction, like Areferences are used'nidentifying' I the apertures 25, 26 and 2l on the opposed Side walls.

Extending upwardly from end portions ofthe top wall II are lugs 28 and29, having transverse apertures 38-3I for the reception of rivet pins 32and 33 for securing the yoke or hood I9 to the slider, the pins 32 and33 passing through the apertures 26 and 21. In assembling the parts, acoil spring 34 is arranged between the end wall 22 of the yoke or hoodand the lug 29, the spring.

normally urging the lock yoke to the right, as seen in Fig. 1, anddownwardly (by reason of the inclination -of slots 26-21) thereby movingthe lock elements I8 into firm engagement with the scoops I1. When theparts are assembled, it will appear that the Surface 35 of the lug 29eX- tends to a point overlapping the elongated aperture 25 to form anabutment against which the inturned coupling ends 36 of a pull 37 areadapted to Strike in the operation of moving the slider to the right, asseen in Fig. 1, or in coup-ling a pair of stringers. However, in theoperation of moving the slider in the opposite direction to uncouple thestringers, the ends 36 of the pull engage the ends 25 of the apertures25 and draw the yoke or hood I9 outwardly by reason of the cam apertures26 and 21 riding on the pins 32-33, thus lifting the lock elements fromengagement with the scoops II.

The top wall II of the slider has between the lugs 28 and 29, elongatedapertures 33 for freely receiving the lock elements I8 and permittinglongitudinal movement of the yoke I9, as above described. It will beunderstood that upon release of the pull, the spring 34 willautomatically return the yoke to bring the lock elements 8 intooperative engagement with the scoops Il.

v In Fig. 3 of the drawing I have shown a slight modification in theform of yoke employed, the

yoke being designated by the reference I 9' and having lock elements I8similar to the elements I8, apertures 25 similar to the apertures 25,apertures 26 similar to the aperture 2,6, and at 39 are shown apertureswhich differ from the apertures 2l in extending straight or parallel tothe apertures 25" instead of inclined, as with the apertures 26'. Withthis construction, the camming action takes place primarily at theforward end of the yoke I9', whereas the rear end portion of the yokeslides back and forth in the elongated aperture 39.1 I

Y. In Fig. 4 of the drawing, I have shown another modication whichdiffers from the structure shown in Figs. '1 and"2, simply in modifyingthe lock` elements I8" to the extent ofV having notches` or recesses 4Don the lower surfaces thereof. These notches or recesses are employed toprovide a more positive engagement with the scoops in retaining theslider against movement along the stringers.

In Fig. 4, the yoke or hood is. identiiied by the reference characterI9", and as the remaining structure `of this hood and yoke are the same,as the yoke I9, no further specific description is given.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:
